Article Synopsis
- - The study examined the presence and genetic diversity of Human Parechoviruses (HPeVs) in 200 children under 15 with Acute Flaccid Paralysis (AFP) in Cameroon from 2018 to 2019.
- - HPeV RNA was found in 11% of the stool samples, with specific genotypes (A1, A4, A5, A10, A14, A15, A17, and A18) identified through advanced genetic sequencing.
- - Results indicated significant genetic variability among the HPeVs detected, suggesting multiple genotypes circulate in Cameroon without associated outbreaks.
Background: The re-emergence of yellow fever poses a serious public health risk to unimmunized communities in the tropical regions of Africa and South America and unvaccinated travelers visiting these regions. This risk is further accentuated by the likely spread of the virus to areas with potential for yellow fever transmission such as in Asia, Europe, and North America. To mitigate this risk, surveillance of yellow fever is pivotal.

- The study investigated the presence of poliovirus types in urban sewage in Cameroon following the withdrawal of Sabin type 2 from immunization in 2016.
- From January 2016 to December 2017, 517 sewage samples were tested, finding no wild or vaccine-derived polioviruses, but vaccine strains were still detected.
- The disappearance of Sabin type 2 from June 2016 onwards indicates successful elimination of WPVs and VDPVs in Cameroon, highlighting the need for ongoing environmental surveillance.
